Men cohabit with less expectation of permanence than women do. Many couples not destined for marriage waste good years in impermanent arrangements, often becoming parents. And, by the way, women do far more housework than men in cohabiting relationships.
Without the basics of security and permanence in their personal lives, people find it much more difficult to rise out of poverty or maintain middle class lifestyles. They are also far less happy. If you care about the poor and the middle class, you ought to worry about marriage.
